If two cans are moving downhill at 12m/s which one will have the greatest kinetic energy? The empty can (3g) or the filled can (7g) explain

The can with the greatest kinetic energy will be the one with the larger mass, assuming both cans have the same velocity.

In this case, the can with 7g of mass will have a greater kinetic energy than the can with 3g of mass, even though they are moving at the same velocity. This is because kinetic energy is directly proportional to the mass of an object.

The formula for kinetic energy is KE = 0.5 * m * v^2, where m is the mass of the object and v is the velocity. Since the velocity is the same for both cans, the only factor that affects the kinetic energy is the mass. Therefore, the can with 7g of mass will have greater kinetic energy than the can with 3g of mass.
